DREDGlNG-BUCKET.

SIECIFIGATION forming part of Letters Patent No. 546,698, datedSeptember 24, 1895. Application filed January 28, 1895- Serial No.536,755- (No model.) I

To aZZ whom it may concern: 7

Be it known that I, ELIJA JOHN FADER, miner, residing at the town ofCalgary, in the district of Alberta, in the Northwest Territories, inthe Dominion of Canada, have invented a certain new and useful Dredging-Bucket; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being made to the accompanyingdrawings, in which Figure 1 is a plan of bucket, longitudinally. Fig. 2is a plan of bucket in operation on a river-section embodying myinvention.

The first part of my invention relates to the bucket and itsconstruction in such a manner that in a river-current, with the aid ofcertain cables, it will swing out into the stream automatically, havingpropeller-flanges attachable for lighter currents and reversible, sothat it can be worked from either bank of a river or stream. It also hasa funnel-shaped month, which on being drawn by that end ashore dips andforces its way into the riverbed, thus filling the bucket with thematerial scraped from the bed of river, this funnelshaped mouth to haveteeth or sharp spikes bolted on when necessary in working on a hard-claystrata. Bucket-barrel and funnelfiange are each made in two pieces andbolted together, so that the whole can be taken apart and packed onhorses to transport across mountainous country. It also has a bottomwith hinge and spring latch, so that when hoisted its contents can beemptied by knocking open the latch.

The second part of my invention relates to the method of workingthisbucket from either bank of a river by attaching to the swivel at theend of draw-irons at the mouth or open end of bucket a hook and pulley,through which works a cable having one end securely fastened on shoreand the other end working in a winch on same shore. To a' swivel on theother or bottom end of bucket is attached a rope or cable fastened tothe opposite shore or anchor out in the stream, it more suitable, and ofsufficient length to allow the bucket to be hauled ashore and emptied,making use of the river-current acting on the bucket-propeller flangesand last-mentioned rope or cable to give to the bucket a revolvingprogressive motion over the bottom or bed of river, swinging it out fromshore in to position, and to hold it against bed of river as it is drawnashore by winch.

In Fig. 1 of drawings, A is the barrel or bucket, of cylindrical form,three feet long, with a diameter of two feet four inches, made ofroll-plate, steel, iron, or aluminium, in two sections, bolted together,as shown at I I and at opposite side of barrel. B is the funnelshapeddipping-flange, made in two sections and bolted together, having a widthof ten inches, a diameter at outer edge of three feet, and inner edgebolted to one end of barrel A. O is the bottom at the other end ofbarrel, opening with a hinge on barrel opposite the spring-latch K,which fastens the bottom when closed. G is a swivel-ring on bottom forattaching cable. D D D are the propellerflanges, bolted to bucket bybraces H H H. Each of these flanges encircles one-third of circumferenceof barrel,are four inches wide near end at B, and eight inches wide atend at 0. They can be reversed to L L and bolted to barrel, so thatbucket can be worked from either side of river. E E E are thedraw-irons, three feet long and one inch thick, bolted to barrel insideof funnel or dippingflange B, having a swivel-ring F at outer end forattaching cable.

Fig. 2 of the drawings represents a section of river with currentrunning in the direction as shown by arrow, and shows the method ofworking the bucket II. At A it is being swung out from shore O D to itsposition at B, when it is ready to be drawn ashore by the cable E F onthe pulley I, one end fastened at M and the other wound on winch G. K isthe rope or cable fastened on shore at L and to rear or bottom end ofbucket, on which it swings out into the stream by paying out the cable EF. If necessary, the cable K can be supported by one or more buoys orlighters, and should the bucket foul on a bowlder or other obstructionit can be relieved by attaching end of cable at M to thelighter N, andby means of the winch G running out the lighter N to the bucket. Thisfailing, bucket can be relieved by the cable K. After bucket is hauledashore it can be hoisted into position over sluice-box P by means ofasnatch-block V foo on triangle 0, and bottom of bucket thrown open byknocking up the latch.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A dredging bucket of cylindrical form with or without the propellerflanges D, D,D,

which are required only in slack currents,

shore at M, working through pulley I and the other end to winch G whichhauls bucket ashore, and with the cable K one end of which is fastenedon opposite shore at L or to an anchor out in the stream and theotherend to swivel ring on bottom of bucket when by paying out the cableE, F the river current acting on cable K and on bucket revolves andswings the bucket out into position ready to be filled and drawn ashore,substantially as and for the purpose hereinbefore set forth.
